Hi,
I upgraded wordpress mu from 1.2.5 to 1.3 this is what I did.
I download 1.3 from the site.
I unzipped the folder and copied its contents to my www folder on the server (where the previous wordpress version was.) I said yes to all when it asked about overwriting.
I then copied the themes folder from a backup i did and overwrote the 2.3 themes folder (so my themes would not change).
I then went to the admin panel and clicked the upgrade site link and it did its thing.
Everything seems good except the categories all gone, and I get this error when I try to add a new category.
"Warning: Attempt to assign property of non-object in E:\wamp\www\wp-admin\includes\template.php on line 52
Warning: Cannot modify header information - headers already sent by (output started at E:\wamp\www\wp-admin\includes\template.php:52) in E:\wamp\www\wp-includes\classes.php on line 738"
What wrong, I really need to get this fixed really soon.
Thanks,
Ben
